Let x be the length of a square. The perimeter of a square is 4x. The area of the square would be x squared.
So the equation would be : 4x=x squared +3
so x squared -4x+3 is now a quadratic.
(x-1)(x-3)
There are two answers to this problem. 1 and 3.
Hope this helped!

4s-3=s^2
s^2-4s+3=0
s=1
4*1-3=1
and
s=3
4*3-3=9
